Image forming apparatus capable of executing image forming jobs having priority levels

Abstract

There is provided an image forming apparatus which can output a job with a higher priority level in a timely manner without processing other jobs first, when a container has been attached to the image forming apparatus. Images on sheets are formed in accordance with an image forming job by a color MFP 104 . The sheets on which the images have been formed is conveyed to a stacker tray 1207 detachably attached to an inserter 108 attached to the black-and-white MFP 105 . Storage of the sheets on which the images have been formed in the stacker tray 1207 is controlled to selectively inhibit or allow the storage according to the priority level of the image forming job by a CPU 1805 of the color MFP 104.

1. An image forming apparatus comprising:
 an image forming device that forms images on sheets in accordance with image forming jobs;  
 a container detachably attached to the image forming apparatus for receiving and storing the sheets of different image forming jobs;  
 a conveying device that conveys the sheets on which the images have been formed to said container; and  
 a controller that controls storage of the sheets on which the images have been formed in said container to selectively inhibit the storage of a next image forming job according to a priority level of a previous image forming job.  
 
     
     
       2. An image forming apparatus comprising:
 an image forming device that forms images on sheets in accordance with an image forming job;  
 a container capable of being detachably attached to the image forming apparatus;  
 a conveying device that conveys the sheets on which the images have been formed to said container; and  
 a controller that controls storage of the sheets on which the images have been formed in said container to selectively inhibit or allow the storage according to a priority level of the image forming job,  
 wherein said controller is operable when the priority level of an image forming job to be executed is lower than the priority level of another image forming job for sheets stored in said container, for inhibiting the storage of sheets for the image forming job to be executed in said container.  
 
     
     
       3. An image forming apparatus comprising:
 an image forming device that forms images on sheets in accordance with an image forming job;  
 a container capable of being detachably attached to the image forming apparatus;  
 a conveying device that conveys the sheets on which the images have been formed to said container; and  
 a controller that controls storage of the sheets on which the images have been formed in said container to selectively inhibit or allow the storage according to a priority level of the image forming job,  
 wherein said controller is operable when thc priority level of an image forming job to be executed is lower than the priority level of another image forming job for sheets stored in said container, for inhibiting execution of the image forming job to be executed.  
 
     
     
       4. An image forming apparatus comprising:
 an image forming device that forms images on sheets in accordance with an image forming job;  
 a container capable of being detachably attached to the image forming apparatus;  
 a conveying device that conveys the sheets on which the images have been formed to said container; and  
 a controller that controls storage of the sheets on which the images have been formed in said container to selectively inhibit or allow the storage according to a priority level of the image forming job,  
 wherein said controller is operable when the priority level of an image forming job for sheets stored in said container is highest, for inhibiting storage of sheets in said container.  
 
     
     
       5. An image forming apparatus comprising:
 an image forming device that forms images on sheets in accordance with an image forming job;  
 a container capable of being detachably attached to the image forming apparatus;  
 a conveying device that conveys the sheets on which the images have been formed to said container;  
 a controller that controls storage of the sheets on which the images have been formed in said containcr to selectively inhibit or allow the storage according to a priority level of the image forming job; and  
 an input device that inputs an image forming job and the priority level of the input image forming job.  
 
     
     
       6. An image forming apparatus comprising:
 an image forming device that forms images on sheets in accordance with an image forming job;  
 a container capable of being detachably attached to the image forming apparatus;  
 a conveying device that conveys the sheets on which the images have been formed to said container;  
 a controller that controls storage of the sheets on which the images have been formed in said container to selectively inhibit or allow the storage according to a priority level of the image forming job; and  
 a setting device that sets the priority level of the image forming job.  
 
     
     
       7. An image forming apparatus comprising:
 an image forming device that forms images on sheets in accordance with image forming jobs;  
 a discharge device that discharges the sheets of different image forming jobs on which the images have been formed by said image forming device; and  
 a controller that controls said image forming device to selectively inhibit image formation of a next image forming job by said image forming device according to a priority level of a previous image forming job.  
 
     
     
       8. An image forming apparatus comprising:
 an image forming device that forms images on sheets in accordance with image forming jobs;  
 a container detachably attached to the image forming apparatus for receiving and storing the sheets of different image forming jobs;  
 a conveying device that conveys the sheets on which the images have been formed to said container; and  
 a controller that controls storage of the sheets on which the images have been formed in said container to selectively inhibit the storage of a current image forming job according to a priority level of a most recent image forming job stored in the container.
